reality check [for dark colours] Pin

One of the techniques for inducing lucid dreaming is about getting one finger perforating the opposite hand. Yet to remember to do so in your dreams you need to repeat this failing action many times during the day when you're awake. That's a reality check. Once you'll succeed in your oniric state, you will be able to wake up in your dream and start to control it. If you start to throb and vibrate violently stay calm, resist, realax and let it pass. Don't focus too much your attention on a single thing.
